WebOkazaki fragment. A short segment of DNA synthesized on a template strand during DNA replication. Many Okazaki fragments make up the lagging strand of newly synthesized … Okazaki fragments are present in both prokaryotes and eukaryotes. DNA molecules in eukaryotes differ from the circular molecules of prokaryotes in that they are larger and usually have multiple origins of replication. This means that each eukaryotic chromosome is composed of many replicating units of DNA with multiple origins of replication. In comparison, prokaryotic DNA has only a single origin of replication. In eukaryotes, these replicating forks, which are numerous all … the poison rose actors

The Concept of Okazaki Fragments by Unacademy

WebOkazaki Fragments are defined as follows: Okazaki fragments are small segments of DNA that are formed when the lagging strand undergoes discontinuous replication, as in the case of a DNA strand break. The length of these pieces in bacterial cells is between 1000 and 2000 nucleotides, whereas the length of these fragments in eukaryotic cells ... WebHow are Okazaki fragments synthesized quizlet? They are formed in the lagging strand. Okazaki fragments are short sequences synthesized in the lagging strand because DNA polymerase can synthesize only from 5 to 3, and the DNA strands are antiparallel. ….
